2. Designed purpose of use
The AVANT Snow blower 1150/1500 is an attachment that is suitable for use with AVANT compact loaders
that are shown in Table 1. The Snow blower is intended to spread snow evenly to the sides of the area
instead of piling it up. The two-phase snow blower is suitable also for professional use, and it is equipped with
a powerful hydraulic system with two separate hydraulic motors for efficient operation even when handling wet
and heavy snow.
As standard, the snow blower chute can be turned electrically 270 degrees directly from the driver’s seat. The
wide adjustment range of the manual throwing height control makes it possible to control the ejection of snow
precisely as needed, either as to pile snow directly to the side of the drive path, or to spread evenly far away.
As an option, electric throwing height adjustment is also available, which can be operated only with the
optional Opticontrol® system of the loaders.
The Snow blower 1150/1500 is not designed for any other use than what is specified in this manual and must
not be used for any other purposes than what is intended for.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional technicians. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT dealer if you have additional questions about the operation or maintenance of the equipment, or if you
require spare parts or maintenance services.

3. Safety instructions for using the snow blower
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful and improper or careless use or maintenance may cause serious personal injury or property
damage. Due to this, all operators must carefully familiarise themselves about correct use and the operator's
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not completely familiarised yourself with its operation and the related hazards.
DANGER
Misuse, careless use, or using an attachment that is in poor condition may
cause risk of serious injuries.
Familiarise yourself with the controls of the loader,
correct coupling procedure, and the correct way to operate the attachment at a safe
area. Study especially how to stop the equipment in a safe manner. Read all safety
precautions carefully.
Read all safety instructions carefully before handling the attachment
WARNING
When attaching an attachment to the loader, ensure that the locking pins of the
loader's quick attach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.
This
attachment is designed to be used by one operator at a time. Do not let others
near the danger area of the equipment when it is in use.

Always transport the attachment as low as possible to keep the centre of gravity low,
and keep the telescopic boom retracted during driving.
Risk of impact from sudden stop - Do not drive at high speed unless you can
be sure that there are no obstacles at the working area.
The loader may stop
suddenly if the snow blower hits an obstacle. Remember that there may be hidden
obstructions or fragile surfaces under the snow. Always use seat belt and drive with
caution.
Risk of thrown objects - Keep a safety distance of at least 2 metres between a
snow blower that is running and any person in vicinity.
Keep in mind that the
snow blower will throw snow and any other objects entering the attachment at high
speed.
The snow blower can throw e.g. small stones even distances over 30
metres.
Stop the snow blower if there are persons or fragile objects at the direction
of the discharge chute of the snow blower.
Risk of thrown objects - Keep the discharge chute directed away from other
persons or fragile objects.
Make sure that the rotation of discharge chute works
smoothly, and that the discharge chute protector and throwing height
deflectors are
securely fastened. Lock the manual throwing height adjustment securely.
Risk of entanglement and severing near the snow blower - Follow safe
stopping procedure before leaving the driver's seat.
Never leave the driver’s seat
when the snow
blower is running or when the auxiliary hydraulics control lever of the
loader is locked on. Always keep hands and feet away from moving parts and use
additional tools to clear any blockage of the blower.
Operate only at well lit areas. Make sure that all lights of the loader are in good
condition, clean, and adjusted correctly. Extra work lights are recommended for the
loader when operating during dark. Mark any obstacle at the work area before
operating the snow blower to avoid collisions.

WARNING
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Pay attention to the contours of the terrain and other hazards, such as
branches and trees that can reach to the driver's area, loose rocks, and slippery
surfaces.
Make sure to use only an attachment that is in good condition. Perform daily
inspections and read the instructions regarding service and maintenance. Never
operate the attachment if the hydraulic systems of both the attachment and the
loader are not completel
y intact. Check the condition of the snow blower rotor
regularly.
Do not leave the driver’s seat when the loader boom is lifted. Going under a raised
attachment or loader boom is dangerous. Always remember that the boom may lower
due to loss of stabili
ty, mechanical fault, or if another person operates the controls of
the loader.
Make sure to use only an attachment that is in good condition. Do not modify the
attachment in any way that could affect its safety.
Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Use the equipment only for its intended purpose. Other use may create unnecessary
safety risks, and the equipment may get damaged.
Make sure that the loader is equipped with necessary safety components, and that
they are in working condition. Seat belt must be used. If there are specific hazards
related to the operating area, use appropriate safety equipment.
Also read the safety instructions and correct use of the loader from the operator's
manual of the loader.
